About

Hyemin Lee

Hi, I'm Hyemin Lee! 👋 I enjoy solving problems and thinking logically, which naturally led me to work as a software engineer. I'm an adventurous individual who also has a passion for photography and travel.

I'm currently interested in CRDT, Zero knowledge proof and distributed system. Beyond these, I love learning and applying any technology that can bring value to people.
